Description

Detachable display device serving as mobile device acover sheet}

The present invention relates to a detachable portable terminal case combined screen output device, comprising a case portion surrounding the portable terminal and a screen output unit for displaying information of the portable terminal, the case can be combined with the portable terminal inside; It is composed of a connection terminal for separating and coupling the screen output unit to the connection terminal and the outer hinge, and is separated into the top and bottom can be combined to fit the mobile terminal and the screen output unit at the same time, the screen output unit is also a rotary hinge The terminal connection is configured to be detachably coupled with the case. The screen output unit can be separated and combined with various types of cases, and when the portable terminal of a different size or type is replaced, the screen output unit with a battery and a display window can be reused by separating the case. The present invention also relates to a detachable portable terminal case combined screen output device capable of operating a program in various modes by driving a combination of a display device provided in a touch screen and a screen output unit of the portable terminal.

In general, a mobile terminal having a touch screen on its front side often provides various functions utilizing a touch screen in addition to a function of a mobile phone, in particular, a smart phone.

The smartphone is equipped with its own operating system and equipped with a large memory, allowing you to directly connect to the Internet through various web browsing programs using the wireless Internet, and freely install or delete various programs (applications) directly. It is equipped with small computer functions such as realizing an interface suitable for itself through various applications.

As described above, since the entire front surface of the mobile terminal having a touch screen is made of a liquid crystal display (LCD), the risk of being damaged by a drop accident or other impact is very high. Therefore, many users purchase and use cases to secure expensive mobile terminals. However, since the length and width of the portable terminal are not standardized and exist in various ways by manufacturers, the cases also have a large number of special cases for the corresponding model, and users must purchase a compatible exclusive case every time the mobile terminal is replaced. There was a problem.

On the other hand, a mobile terminal made of a touch screen such as a smart phone provides various advanced functions as described above, but since the portability is also important, the size of the touch screen is limited to a maximum of about 4 inches. In spite of such excellent performance, there are inefficient and inconvenient problems in running various programs, using as an e-book reader, writing a document or writing short texts due to the limitation of the screen.

In order to solve this problem, Japanese Laid-Open Patent Publication No. 1104-354789 (published on January 11, 2006) discloses a display function expansion device having a separate extension screen attached to a portable information terminal. However, Japanese Laid-Open Patent Publication No. 1104-354789 merely provides a large extended screen to replace the screen of the portable information terminal itself, so that the information content of the portable information terminal is simply displayed on the extended screen to display the screen of the portable information terminal itself. There is a limit to the effective use of both the screen and the extended screen.

In addition, Korean Patent Laid-Open Publication No. 10-2010-0084941 (published on July 28, 2010) proposes a portable terminal case provided with a touch screen, which only describes the use of the touch screen as a keyboard. There is a limit to the efficient use of the combination of the portable terminal and the touch screen of the case.

The present invention is to solve the problems described above, by configuring the case and the screen output unit detachable structure, it can be safely protected regardless of the size, such as the length or height of the mobile terminal, and a separate auxiliary battery The present invention provides a detachable portable terminal case combined screen output device that can be used in conjunction with a touch screen of the portable terminal by providing an embedded display device.

Another technical problem to be solved by the present invention is to configure the case and the screen output unit can be separated into a structure, combined with a screen output unit of various sizes and a case of various sizes, through the case acting as a screen output unit and a gateway It is combined with portable terminals of various sizes. In addition, when the portable terminal is replaced, only a case suitable for the replaced portable terminal is purchased, and a display unit with a built-in display window and a battery can be reused, and a display device provided with the touch screen and the screen output unit of the portable terminal can be used for various purposes. The present invention provides a detachable portable terminal case combined screen output device that can be arbitrarily selected and used by a user by providing a driving mode combined with each other.

The detachable portable terminal case combined screen output device for solving the above-described technical problem is a case surrounding a portable terminal, the case comprising a connecting terminal which is formed inside the case and can be coupled in correspondence with the position of the terminal connection port of the portable terminal, A hinge connection terminal formed at an outer lower hinge and capable of coupling in correspondence with the position of the terminal connection port of the screen output unit; A display output unit body including a display window and a battery that is fitted and coupled to the hinge connection terminal, and a connection portion consisting of a portable terminal case terminal connection port and an electric circuit for transmitting various signals and data between the display window and the battery configured in the screen output unit Characterized in that the configuration.

In addition, a mode switch that selects a plurality of modes to be combined by combining the touch screen of the mobile terminal and the display device of the screen output unit is formed on the screen output unit, and uses the touch screen of the mobile terminal as a keyboard and the display device of the screen output unit. Keyboard mode using the display as a main display device for displaying various kinds of information, an extended mode for displaying information using a display device of a touch screen of a mobile terminal and a display unit as a continuous display device, and a touch screen of a mobile terminal. It is preferable to use a display device of the display output unit and the screen output unit as independent display devices so that a user can arbitrarily select any one of the individual modes for displaying individual information.

In this case, the screen output unit processes and calculates a variety of information to drive the mode selected by the mode switch, and separately formed a microprocessor device for transmitting and receiving various signals and data associated with the mobile terminal and the selected mode through a cable connected in the case It is good to be able to operate smoothly without burdening the portable terminal.

The present invention has a structure in which the case and the screen output unit can be attached and detached, and one screen output unit having a predetermined size is combined with the case of the mobile terminal of various sizes, and various sizes via the case acting as a gateway between the screen output unit and the mobile terminal. The portable terminal and the screen output unit can be separated from each other, there is an advantage to protect the portable terminal regardless of the specifications. In addition, when replacing the portable terminal, only buy a case for the portable terminal to be replaced, the display unit including the display window and the battery can be reused.

In addition, the present invention is provided with a display device and a battery in the screen output unit, overcoming the narrow touch screen of the mobile terminal itself can be used to arbitrarily select a variety of modes according to the driving program or various situations by interlocking the two display devices together There is another advantage.
